54题、choose two

Which two statements describe the relationship between a scheduler window, a resource manager plan, and a job class?

A) A scheduler window specifies a job class that will be activated when that scheduler window becomes active.

B) A scheduler window together with a job class, controls resource allocation for a job using that job class in that scheduler window

C) A job class specifies a scheduler window that will be open when that job class becomes active.

D) A scheduler window can control resource allocation by itself.

E) A scheduler window specifies a resource manager plan that will be activated when that scheduler window becomes active.

Answer：BE

(解析：Job Classes 相当于创建了一个job 组，DBA 可以将那些具有相同特性的job，统统放到相同的Job Classes中，然后通过对Job Class 应用ORACLE 中的"资源使用计划"特性，就可以对这些job 执行过程中所需要的资源分配情况进行管理。)
